Fertilizer for preventing tobacco bacterial wilt and increasing yield

Abstract

The invention discloses fertilizer for preventing tobacco bacterial wilt and increasing the yield. The fertilizer comprises the following raw materials: cow dung, sheep dung, fish maw and gut, brewers grain, omphisa fuscidentalis hampson powder, arborvitate tops, katsuratree barks, tea straws, urea, superphosphate, monoammonium phosphate, potassium nitrate, potassium sulphate, potassium chloride, borax, zinc amino acid chelate, ferrous amino acid chelate, copper amino acid chelate, manganese amino acid chelate, molybdenum amino acid chelate, sodium metasillcate, chromium yeast, nanometer cobalt, gama-polyglutamic acid, polyaspartic acid, phosphorous acid, 3,4-dimethylpyrazole phosphate, a compound water-preservation agent and a microbial agent. The fertilizer organically combines four major functions of tobacco fertilization balancing nutrition, element cooperatively reinforcing function, biological antagonism restraining germs and soil conditioning preventing and treating source, greatly improves the prevention effect on tobacco bacterial wilt, and meanwhile has the effects of water retention and yield increasing.

Description

technical field [0001] The invention relates to the technical field of fertilizers, in particular to a fertilizer for preventing tobacco bacterial wilt and increasing yield. Background technique [0002] Nicotiana is an annual or limited perennial herb of Solanaceae, with a slightly lignified base. Native to South America, it is cultivated all over the world. In China, as an important pillar industry in the economic field, the annual profits and taxes paid by tobacco account for 6% of fiscal revenue. The tobacco tax and profits paid by tobacco companies are nearly one trillion yuan a year. [0003] It is driven by economic interests that tobacco is still an important agricultural product among commercial crops despite the fact that smoking is harmful to health. However, due to differences in climate, soil, and uneven planting and management levels of farmers, various diseases in tobacco planting have become increasingly serious, especially tobacco bacterial wilt, which has...

Problems solved by technology

However, the main reason for the frequent occurrence of tobacco bacterial wilt is that repeated cropping and unreasonable fertilization lead to two levels of soil pH, poor drainage and air permeability, imbalance of microbial colonies, and weakened plant resistance

There are many methods of prevention, such as: crop rotation, chemical control, biological control, etc., but a single control method often has little effect
